Definitions
- composition of antibodies directed against the human or animal interleukin-2 receptor Composition of antibodies directed against the human or animal interleukin-2 receptor.
- the present invention relates to a composition
- a composition comprising at least two antibodies directed against the human or animal interleukin-2 receptor for ensuring the inhibition of interleukin-2 binding
- Interleukin-2 plays a vital role in regulating the immune system. We know that two membrane glycoproteins are involved in the binding of IL-2. It is the p55 chain ( ⁇ chain of
- a number of monoclonal antibodies have already been made against the p55 chain in humans and animals. Some of these antibodies have been used in the treatment of diseases associated with lymphocyte activation, such as experimental autoimmune diseases (12, 13), T cell leukemia (14) and, most importantly, organ transplants ( 15): The efficacy of a monoclonal anti-p55 antibody, 33B3.1, has been demonstrated in the prevention of early rejection of kidney allografts in humans (16 to 18).
- a number of anti-p75 monoclonal antibodies are also known, notably TU27 (19), Mik ⁇ 1 and Mik ⁇ 2
- anti-p75 monoclonal antibodies in particular the TU27 antibody
- the applicant found that the antibody did not affect not proliferation of cells when the IL-2 concentration covered the saturation level of the high affinity receptors, which suggests a level of inhibition weak or zero in vivo in the presence of IL-2.
- anti-p55 antibodies such as 33B3.1 only induce complete inhibition of IL-2 binding at high concentration (> 100 nM).
- the present invention therefore aims to provide an antibody composition, preferably monoclonal, inducing at low concentration an effective inhibition of the binding of IL-2 and of the proliferation induced by IL-2.
- the Applicant has surprisingly found that the combined use of two anti-p55 and anti-p75 monoclonal antibodies respectively has a synergistic effect which results in a very strong inhibition of cell proliferation at much higher antibody concentrations. weak than what was used in the prior art for lower results.
- the inhibitory effect of 33B3.1 on the proliferation induced by IL-2 is greatly facilitated in the presence of Tic-1, TU27 or A41, the inhibition of 50% of the proliferation being then obtained at 33B3.1 concentrations 10 to 25,000 times lower.
- the subject of the invention is therefore a composition comprising at least two antibodies directed against the IL-2 receptor, characterized in that it comprises an anti-p55 antibody and an anti-p75 antibody ensuring the inhibition of the binding IL-2 to its receptor and cell proliferation.
- antibody in the sense of the invention means both the antibodies themselves and antibody fragments such as Fab, FCab ') 2 and F v . These fragments can in particular be obtained by chemical or genetic means.
- the anti-p55 antibody and / or the anti-p75 antibody are preferably monoclonal antibodies.
- IL-2 receptor in the sense of the invention is meant both the high affinity receptor constituted by all of the chains p55 and p75, than the said chains alone, in particular the chain p75 'which has an intermediate affinity allowing the binding of IL, -2.
- anti-p55 antibodies in particular 33B3.1
- anti-p75 antibodies in particular TU27, Tic-1 and A41.
- the invention also applies to combinations of anti-p55 and anti-p75 antibodies which have been modified chemically or by genetic recombination, including “humanized” chimeric antibodies, for example by the method described in the application for Patent FR-A-2,641,468, as well as to bispecific antibodies which can be derived from anti-p55 and anti-p75 antibodies, by known chemical or genetic methods.
- the relative proportions of anti-p55 and anti-p75 antibodies can vary quite widely.
- the ratio can range from 99/1 to 1/99, the optimal ratio being estimated at 63 + 20/37 + 20.
- the proportions for other combinations can be determined by in vitro tests or calculated from the optimal ratios of the combination 33B3.1 / TU27, in proportion to the respective affinities for the IL-2 receptor.
- the optimal ratio is estimated at 20 ⁇ 10/80 ⁇ 10; in combination 33B3.1 / A41, the optimal ratio is estimated at 80 ⁇ 10/20 ⁇ 10.
- composition according to the invention can be used in particular as an active agent against rejection of organs and marrow transplants, against leukemias and lymphomas
- CD25-positive as well as against autoimmune pathologies such as type 1 diabetes, rheumatoid arthritis, ankylosing spondyloarthritis, multiple sclerosis and myas thenia gravis.
- a subject of the invention is therefore also a process for the treatment of these diseases in which the composition which is the subject of the invention is administered parenterally, in particular intravenously, preferably between 1 and 50 mg per day in an isotonic vehicle containing the appropriate excipients.

- the 4AS clone comes from a series of clones produced by limiting dilutions from a rejected kidney allograft (22, 23). It was grown in RPMI 1640 medium (GIBCO, Glasgow, Scotland) supplemented with 10% human serum (CTS, France) and 1 nM of rIL-2 (Roussel Uclaf) and was stimulated for one week in the presence of B cells transformed by EBV and irradiated. These B cells were isolated from splenocytes from the kidney graft donor and are available from the same authors. This cell line (called DAB cell line) was cultured in RPMI 1640 medium supplemented with 10% fetal calf serum (SEBAK, Paris, France).
- PBL Peripheral blood lymphocytes
- the monoclonal antibody TU27 is a mouse IgG1 directed against the p75 chain of human rIL-2 (19). It was purified from ascites liquid (supplied by K.Sugamura, Tohoku Univers ity, Japan) by affinity chromatography on a protein A column (Bio-Rad, Richmond, USA), dialyzed against PBS, then the samples were stored at -20oC.
- the TU27 antibody was deposited under the reference FERM P 10509, FERM BP 2510 with the Japanese collection: Fermentation Research Institute (FRI), 1-3, Higashi 1-chome, Yatabe-machi, Tsukuba-gun, Ibaraki-ken 305 Japan.
- the monoclonal antibody 33B3.1 is a rat IgG2a directed against the p55 chain of human rIL-2 (24, 25) and is marketed by IMMUNOTECH (France) under the name IOT 14a (Deposit no 1-1002 with the CNCM ).
- the Tic-1 antibody is a mouse IgG directed against the p75 chain of human rIL2. It is sold in purified form reference M-100A by Endogen laboratories (Boston, MA, USA).
- the A41 antibody is a mouse IgG1 directed against the p75 chain of human rIL2. It was supplied in purified form by U. Weidle from Boehringer Laboratories (Penzberg, Germany).
- the IL-2 used is a highly purified recombinant molecule produced in Escherichia coli and was supplied by Laboratoires Roussel Uclaf, Romainville, France.
- IL-2 coupled to iodine 125 comes from New England Nuclear (Boston, Massachusetts, USA). Its specific radioactivity is between 300 and 1000 cpm / fmol. Tic-1, TU27, A41 and 33B3.1 were labeled with iodine 125 by the iodogen method (26). The specific radioactivity was between 1500 and 2500 cpm / fmol.
- the 4AS cells are subjected beforehand to a "washing" of the IL-2 by preincubation for two hours at 37 ° C. in a medium free of IL-2. The cells were then centrifuged, washed three times and resuspended in PBS containing 0.5% BSA. 25 ⁇ l samples per well of cell suspension (between 0.5 and 2.10 cells per well as appropriate) were distributed on 96-well plates (NUNC, Roskilde, Denmark), with increasing concentrations of labeled ligand in a final volume of 50 ⁇ l per well.
- the cells were prepared and distributed as above.
- the labeled ligand was added in a fixed concentration to increasing concentrations of unlabeled competitors. After incubation at 37oC for 30 min (IL-2) or 45 min (antibody), the bound and non-bound fractions of the cells were determined as described above.
- the 4AS cells were distributed in 96-well plates in an amount of 10,000 cells per well in 200 ⁇ l of RPMI 1640 medium + 10% human serum. Stimulating cells (20,000 irradiated DAB cells per well) and various concentrations of IL-2 were then added. After 72 h of incubation at 37 ° C in an incubator, the cells were incubated for 16 h in the presence of tritiated thymidine (0.25 ⁇ Ci per well) (Amersham, Les Ulis, France), harvested (PHD harvester, Watertown, Massachusetts, USA) and the incorporation of thymidine was then determined.
- the PBL stimulated in PHA or OKT3 were distributed in 96-well plates under the same conditions as the 4AS.
- IL2 was added at 250 pM and optionally anti-rIL2 antibodies at different concentrations.
- the incorporation of thymidine is carried out as for the 4AS cells.
- the antibody 33B3.1 which is inactive towards YT.2C2 cells due to the absence of the p55 chain, exhibited an inhibitory effect much superior to TU27 on the binding of IL-2 to 4AS cells.
- the antibody 33B3.1 induces the complete disappearance of the high affinity component.
- the number of binding sites with intermediate affinity (2500 sites / cell) was similar to the number of binding sites with high affinity measured in the absence of 33B3.1, suggesting that 33B3.1, by binding to p55, has for effect of transforming high affinity structures by liberation of the intermediate affinity component.
- the response curves as a function of the doses of antibody showed that 33B3.1 inhibited the proliferation induced by IL-2 of the 4AS cells (FIG. 4A) with a half-maximal effect observed at 7.5 nM.
- Complete inhibition of proliferation by 33B3.1 was observed only at high concentration (> 100 nM).
- the dose-response curve of 33B3.1 was widely shifted to the low concentrations. In this case, the semi-maximum inhibition of proliferation was obtained with only 0.2 nM of 33B3.1, that is to say approximately 40 times less antibodies.
- FIG. 4B Other experiments (FIG. 4B) have shown that, while TU27 alone at significant concentrations of 50 pM at 320 nM, with or without preincubation, had no effect on the proliferation induced by IL-2, this antibody showed an inhibitory effect in the presence of 33B3.1.
- the antibody 33B3.1 at 25 nM induces an inhibition of approximately 70% of the proliferation and the remaining 30% are completely inhibited by TU27 (half-maximum effect observed at 1 nM).
- Binding experiments carried out on a cell ul area expressing only the human p75 chain (YT line clone 2C2) (reference 4) have shown that the antibodies Tic-1, TU27 and A41 recognize a common epitope on the p75 chain with respective affinities of the order of 10 nM, 1 nM and 0.1 nM.
- FIG. 5A shows that the inhibitory effect of 33B3.1 on the proliferation of 4AS cells is all the more effective when it is associated with a high affinity anti-p75.
- the 33B3.1 used alone partially blocks (30%) proliferation at the highest concentration (167 nM), with an IC50 estimated at 1430 nM.
- the IC50 of 33B3.1 drops respectively to 102 nM, 2.3 nM or 0.056 nM, i.e. at concentrations respectively 14 times, 620 times or 25,500 times less important than in the absence of the corresponding anti-p57.
- anti-p75 antibodies cause very little inhibition of the proliferation of 4AS cells in the absence of 33B3.1.
